Abstract
Exploring an electrocaloric (EC) material with a large electrocaloric effect (ECE) value is of high interest and importance to realize a solid-state cooling solution. We have investigated the electrocaloric performance and energy storage density in lead-free (1-x)\(\text {K}_{0.5}\)\(\text {Na}_{0.5}\)\(\text {NbO}_{3}\)-x\(\text {BiScO}_{3}\) (KNN-xBS) ferroelectric ceramics. The KNN-xBS (x = 0.01, 0.02, 0.03, and 0.10) ceramics were synthesized by the typical solid-state route and ECE was examined by an indirect method based on Maxwell’s relations. The maximum value of ECE has obtained 0.61 K at 428 K for 60 kV/cm applied field, and the recoverable energy density has 0.57 J/\(\text {cm}^{3}\) for x = 0.01 ceramics. The obtained positive ECE has a larger value among different lead-free ceramics. The \(\text {BiScO}_{3}\) doped \(\text {K}_{0.5}\)\(\text {Na}_{0.5}\)\(\text {NbO}_{3}\) ceramics have presented enormous potential in solid-state cooling technology for a cleaner environment.
期刊介绍:
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
